Patches 2 and 3 turned up while checking the nearby TPS65214 code. Patch 1 fixes TPS65219 input reads. Patches 2 and 3 fix TPS65214 direction handling. I tested the series under x86_64 QEMU 10.2.1 with a temporary KUnit suite and a RAM-backed regmap. Both tests failed on the base commit. The TPS65219 input-high test returned low, and the TPS65214 direction-output test left GPIO_CONFIG clear. Both tests pass with this series. A W=1 build of drivers/gpio/gpio-tps65219.o also passes. The KUnit suite is not included. It tests the driver logic, not real PMIC hardware. I have not tested this on real hardware. Testing on affected hardware is welcome.
